ENVELOP-CUTTlNG MECHANISM.

Specification of Letters Patent.

Patented May 14, 1907.

Application led February 9. 190'?. Serial No. 356,590.

To all wil/nm t may concern:

Be it known that i, Annan A. RMEUTAN, a citizen oil' the United States,residing at Worcesten in the eounty ol lVorcester and State oflVlessaehusel-ts, have invented a new and useful Envelop-UuttingMechanism, ol' which the 'following is a specification, reference beingmade therein to the aoeornpanying drawings.

The prime object of my present invention is to provide a convenient andellleient means for accurately cutting out the internal angle forms onenvelop blanks; said means having facilities for rectangular enlargementand reduction whereby it is adjustable for many dillerent sizes and forenvelop blanks oi various shapes and styles.

Another object is to provide an envelop cut ting mechanism of thecharacter described, with an attachable and detachable supplementalextension appliance for use in eutting blanks having an extra long liep,or ier sidesearned envelope and the like. Y

Another object is to provide an envelop cutting die or means for cuttingout the iternal angle forms of envelop blanks, with a detachableinterset cutting ap iliance for eutting an opening or slit in tie areaoi the blanks; as for outlook envelops, or similar purposes.

attain these objects by the mechanism illustrated in the accompanyingdrawings, wherein Figure i represents a top plan view of the mechanismembodying my invention. Fig. 2 is an elevation view of the same. Fig. 31s a sectional view at line XX showing the interset cutting appliances,and Fig. 4 represents a transverse section of a device for lookingtogether the edges of the main and extension blades.

It will be understood that this improved mechanism is adapted as acutting-die to he employed in a cutter-press having a Hat platefollower, such as are commonly used when cutting paper and othermaterial with dies.

The cutting-blades are made of uniiornn height with straight or leveltop and bottoni' edges to match the plate of the cutter-press.

My improved mechanism, as sliovvn in the drawings, comprises the fourcorner seetions or blocks indicated by reference numerals l, 2, 3, 4,each carrying a cutter-blade of suitanle angular shape ou plan, saidblades each having its top edge approximately square and llush with thetop surface of the section block, and its lower edge properly ground toa cutting edge, The cutter blades, respectively ind leatcd at (l1, C2, Cand C4, are formed with an angle contour 5 of the desired shape lor theinternal angle forms to he out from the envelop blanks, and with wingportions 6 and 7 that extend in either direetion approximately as shown.The vving portions 7 are shown in parallel planes, and the portions 6 lnplanes inclined toreaoh other g but these forms may he modified in seineinstances for peculiar styles of blanks. The dotted line e indicates thefold line re resenting the 'aee area of an envelop for W ich the euttersare at present adjusted. *so

ln practice the blades are ahout three and one half inehes in depth, andthe corner hloolis about one inch, more or less.4 The hlades are scouredto the blocks hy screws, as indieated hy dotted lines on Fig. 1. Thei'our corner sent-ions are connected by rods in a manner for adjustmentthereon. Each corner section is provided with a guide rod having its endri id ly fixed therein, and ex tending horizonte ly and in rectangularorder, with a slidahle lit through an opening in the o posite or nextadjacent corner seetion. Tiese rods are indicated at D1, D2, Darand D4.The end of the rod can he secured hy a nut, as at S, or can he threadedinto the metal of the bleek, as at S); or it may he otherwise linedtherein. Each Vcorner seetion is provided with a set-screw or means forfirmly clamping the guide rod that passes through it, as indicated atFi, F2, F'El and F'. The outer sides of the rods are best slahbed oilflat to give a square seating face for the end ol the set-screw. Themide rods can be of any convenient length desired. By loosening theclamping means F2 and F* of the corner sections 2 and 4, the transversedimension between the cutter-blades can he increased or reduced; and byloosening the Clamping means Fj and F3 of the @orner seetions 1 and 3,the longitudinal dimension he- Vlsveen the cutter-blades een he enlargedor reduced. Thus the die or cutting means may he adjusted for any sizeor proportional forni of rectangular envelop shapes. At all positions ofadjustment the parts maintain their rectangular relation, and theadjustment is eleeted Without changing the relative singularity of thecutting blades in respect to the longitudinal and transverse axes of thedie.

For instances wherein the envelop blanks ICO are to have an extra longllap, l provide the mechanism with a supplemental extension appliance,which consists ol' two carriers or brackets 12 and l, cach having anextension blade 1T attached thereto, the end ol' which is adapted toabut against the end ol' the regular cutter-blade at Yl5. One oll saidcarrier-llocks 12 is fitted to slide onto and be clamped by the screw llto one ol' the guiderods, as l)'*, and is provided with a transverselyprojecting rod 1G Vfixed therein, and upon which the othersupplemental-blade carrier i3 is adjustably secured by a suitable clampdevice and screws 1E), This construction permits adjustment of thecritter extension members to (io-operate with the lateral enlargement orreduction of the lnain portion ol' the mechanism. The extension can beused at either end of the die. The carriermembers 12 and 15% arepreferably made to lap onto the main cutter-blade and have one or morebolts 1S that screw thereinto7 as indicated. At the adjacent ends l5ofthe blades I provide means for locking them together to prevent theirspringing out ot alinement. lt consists of a disk 2() having an inwardlyofi'- set peripheral lange 2l. and a central threaded stud 23. Athreaded o )ening is formed at the joint, hal i' in each bladeJ (seeFigs. 2 and Lt) and a circular grooved recess 25 is formed in the bladesto correspond with and receive the disk. When screwed into place thethread holds the two blade sections in line, and the groove 25 andflange 21 prevents their spreading apart endwise. The mechanism can beemployed with or without this supplemental extension appliance accordingto the requirements of the work to be performed.

For some classes of envelops it is desired to eut an opening or slit, ofsome torni7 within the area of the blank. For such purpose I provide adetachable interset cutter 30 having an arm or supporter 32 that isadjustably securable to any one ot the guide-rods that connect thecorner sections. In the present instance I show the interset cutter 30formed for cutting what are known as outlook7 openings in the blanks.Said cutter is attached to the slotted arm 32 by bolts 33, and said armis clamped to the rod D by the binding screws S4, or other eicientmeans. The cutter 3() can be made of any required form for cutting ahole or slit, one or more as required, and its supporting arm 32 can bemade for giving the cutter such osition as may in any instance bedesired. t may also be used in connection with either of the guide rods.The l'nterset cutter can be omitted in instances where no openings orslits are to occur in the blanks.

What I claim as my invention and desire to secure by Letters Patent, is

1. A mechanism of the character specified, comprising a series of fourcutter-supporting corner blocks having bladeseating laces in approximateconformity to the respective angle planes, a series oi' horizontallydisposed guide-rods arranged in rectangular order extending through andadjustablyY connecting adjacent blocks, an angle-cutting blade attai-hed to the seating l'aees on each oll said corner blocks, and meansl'or securing the respcetive corner-blocks and guide-rods at positionsof adjustment in relation to eat-h other.
